Abstract

L'invention concerne un robinet à tournant comprenant un corps de robinet doté d'un orifice d'entrée, d'un orifice de sortie et d'une chambre centrale s'étendant entre l'orifice d'entrée et l'orifice de sortie. Le robinet comprend également un segment de joint d'entrée à l'intérieur de la chambre centrale et comprend un alésage s'étendant à travers celui-ci et aligné avec l'orifice d'entrée. Un segment de joint de sortie est disposé à l'intérieur de la chambre centrale et comprend un alésage s'étendant à travers celui-ci et aligné avec l'orifice de sortie. Un organe de tournant est disposé dans la chambre centrale et peut être déplacé entre une position ouverte, pour faciliter l'écoulement de fluide à travers le robinet à tournant, et une position fermée, pour bloquer l'écoulement de fluide à travers le robinet à tournant. Des premier et deuxième segments latéraux sont disposés entre et imbriqués avec les segments de joint d'entrée et de sortie de façon à encercler l'organe de tournant. Les segments latéraux sont mis en tension afin de précharger les segments de joint contre l'organe de tournant pour empêcher l'écoulement de fluide entre les segments de joint et l'organe de tournant.
